    上海人民電氣有限公司介紹斷路器與隔離開(kāi)關(guān)的區(qū)別

    2020/8/24 11:01:36      點(diǎn)擊:

    一、斷路器與隔離開(kāi)關(guān)的區(qū)別:

    1、斷路器有滅弧裝置,故斷路器能夠帶負(fù)荷操作,不但能操作負(fù)荷電流,還能操作故障(短路)電流;而隔離開(kāi)關(guān)沒(méi)有滅弧裝置,雖然規(guī)程規(guī)定其可以操作于負(fù)荷電流小于5A的場(chǎng)合,但其總體屬于不能帶負(fù)荷操作。

    2、斷路器有良好的封裝形式,故單純觀察斷路器,不能直觀地確定其是處在閉合或斷開(kāi)位置。而隔離開(kāi)關(guān)結(jié)構(gòu)簡(jiǎn)單,從外觀上能一眼看出其運(yùn)行狀態(tài),檢修時(shí)有明顯斷開(kāi)點(diǎn)。
